Bridges world-wide have Goodwin manufactured structural and support castings incorporated in them.

Cable band castings are supplied fully machined, painted and vulcanised together with the associated bolting. Recent supply includes the Oakland Bay Bridge in California, USA and the Hardanger Bridge in Norway. Goodwin have also supplied componants for the Tsing Ma Bridge in Hong Kong harbour and the Jiangyin Bridge over the Yangtze river in China.

Hardanger Bridge is a suspension bridge under construction which will cross the Hardangerfjord in southwestern Norway. The bridge will be 1380 metres long, with a main span of 1310 meters.

2x12,000kg, GX3CrNi13/4 steel cable saddle castings for the Hardanger Suspension Bridge in Norway. These castings will sit atop of the 200m towers at either end of the bridge.

26,000kg, finished assembly of one the cable splay saddles. The CrNi 13/4 castings are welded to the carbon steel fabrication. The welded joint incorporates a welded nickel alloy 625 intermediate layer.

The San Francisco - Oakland Bay Bridge is a pair of bridges spanning San Francisco Bay of California, in the United States. It carries approximately 270,000 vehicles per day on its two decks. The eastern span of the bridge is currently undergoing a seismic retrofit following earthquake damage.

B4 type cable band in carbon steel, manufactured for the Oakland Bay Bridge. The assembled weight is 2,000kg.

The Jiangyin Yangtze River Highway Crossing consists of a long span six-lane suspension bridge. The main span of the bridge is 1,385m, making it the fourth longest in the world when constructed, now the sixth longest.

Corrosion protection of cable bands is vital to the long-term life of a suspension bridge. Metal spraying with zinc is followed by further protection from sea water corrosion with a multicoat two-pack epoxy resin paint system. Both metal spraying and painting is carried out at the Goodwin facility.

The Tsing Ma Bridge carries two three-lane carriageways on top of another twin lane carriageway next to a twin track railway line. At 2.2km long with a 1,377m main span it is the world's longest suspension bridge carrying both road and rail traffic.
